TO ALL PERSONS T0 WHUM THESEV PRESENTS SHALLl Be it known that I, ELIsKA T. COLBUBN, of Boston, in the county of 'Sutolln of, the State of Massachusetts, have made a new and useful improvement in Railway Carriage Windows, or the sashes theref; and do hereby declare the same'to be fullv desoribediuthe following specicatiomnnd ,represented in the accompanying drawings, of whichi Figure 1 is anv inner side elevatien'jand y i Figui-e2, an external'view f a window provided withixnyigvjentiera# x Figure 3 is a verticalend longitudinalsection offrit."

Figure 4 is ahorizontal and transverse section andA V n Figure 5 is a transverse and vertical sectio'nio: it,lwith'itsia1 nxilihat'y 'sashes'pe-n.

The pur'pose of lmy invention is to insure ventilationef,theearriagmA and p'rotection of the eyes and face of a passenger or person therein from dust, smoke,"r einde-rs.l l v n l y In the drawings, A dexites -a window frame,vwhich sito be furnished withtwo sash'es, one of which only, viz, that which is movable iartlcally withinithe frame, -.1s represented in theg'l'res. This sash is shown at B as having two `auxiliary"saslles, C C7, eaelrdfwiiohi to be g'lazecfwitircne" or more panes'oglnss. The auxiliary sash, C; is to be connected to one of the. upright bars of the main sash, B, by means of hinges, a a, so as to enable the sash, C, to be swung outward. The two auxiliary sashes are to be hinged together at their two inner edges. 'Furthermore there project outwardly from the sash C two round studs,b b, one of which goes upward, and the other goes downward from ,the sash, this arrangement being-as showuin tig, 3. Each of them enters a slot, o, made in a'pi'ece of metal, d, xed to the main sash, the slot being arranged parallel to the outer side -of the main sash.- The window frame has' one of its sash-receiving grooves, lviz,pthat marked e, somewhat deeper than the other, or that marked the same being to enable the sash, C', to enter such groove, and to extend therein, when closed as well as'when open. This is for the purpose of causing the space that there is between the sash and the next adjacent vertical bar of the main sash, when the auxiliary sashes are opened, to be covered by -the window frame. To the hinge-pin or rod,g, of the two auxiliary sashes I apply a hasp, E, made like a trunk hasp. It has two catchholes, s k, made through it, one being made in each of its legs. Y' They are to receive a small pin or stud, l, projected upward from the middle of the lower bar of the,

main slash. The hasp and the pin serve ,to hold the auxiliary sashes, either opened or closed. When open they stand at an obtuse angle to each other, as represented in figs. 4 and 5, in which case air can enter the carriage, or leave it, through the triangular open spaces whieh willrthe're be forined between the horizontal bars of the main and auxiliary. sashes. In case the stationary main sash be arranged ver and in advanceof the main sash, the latter maybe raisedfin its grooves, provided the auxiliary sashes be closed; but by arranging the stationary or upper main sash in'r'earoi' the lower main sash, so that the latter, while being elevated, may pass up in front of the former, the said upper sash lwill afford no impediment` to the elevation of the lower sash, when the auxiliary sashes thereof may heupen. A window may be made by applying the savshes to Athe''windowtrame iny 'the samemanner as the auxiliary sashes,0 and C', are arranged with and applied to the main sash B; but for railway car windows I prefer the retention of thel main sashes.

I clai1n t`e arrangement and application of the, auxiliary sashes, 0 C', with the window sash B, orl its equivalent, substantially in manner and by means as specilied. y l

I also'elaim the combination, as well 4as the arrangement, of the window frame, thel main sash B, and the auxiliary sashes C C', applied together and to the nain sash, siibstantiallyas specified.
